CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 765,091, dated July 12,1904.

Application iiled July 1O 1901.

To all whom it may concern;

Be it known that I, HERBERT M. LOURIE, a citizen of the United States,residing at Keokuk, in the county of Lee and State of Iowa, haveinvented a certain new and useful Improvement in Cream-Separators, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to a cream-separator, my object being to provide animproved construction of cream-separators of that class in whichamilk-reservoir is adapted to be immersed in a reservoir containing coldwater or ice whereby, due to the chilling effect, the cream is caused toseparate from the milk and to accumulate at the upper end of themilk-reservoir. In cream-separators of this class it is usuallydesirable to have the milkreservoir so constructed that the same can belifted out of the water-reservoir, in which it is adapted to normallyrest. This removal is desirable in order that the reservoirs may bethoroughly washed and cleansed. In milkseparators as commonlyconstructed heretofore the exit-pipe of the milk-reservoir is providedat one of the lower corners thereof and is adapted to extend verticallydownward, passing through a suitable opening in the bottom of thewater-reservoir, a faucet being attached to the lower end of theexit-pipe beneath the bottom of the water-reservoir. In order to removethe milk-reservoir, it is necessary to detach the faucet, and themilk-reservoir may then be withdrawn, the exit-pipe thereof beingwithdrawn from the opening extending through the bottom of thewaterreservoir. This construction is objectionable, since itnecessitates the detaching of the fancet from the exit-pipe when it isdesired to remove the milk-reservoir. Moreover, the withdrawal of theexit-pipe from the opening in the bottom of the water-reservoir permitsthe water therein to escape. Again, since the exit-pipe passes throughthe bottom of the water-reservoir it is necessary to provide Serial No.67,791. (No model.)

a special support for the structure permitting the placing of thereceptacles into which the milk and cream are discharged beneath thebottom of the water-reservoir.

It is the object of the present invention to provide a structure whichwill overcome these various objections, and in accordance with thepresent invention I provide a separable exit pipe or duct, one partthereof being carried upon the milk-reservoir and the other part uponthe water-reservoir, whereby the milk-reservoir may be readily liftedfrom the water-reservoir and the parts of the separable exit-pipethereby separated without other manual manipulation.

In the preferred form of my invention I mount the portion of theexit-pipe carried upon the water-reservoir so that the same will extendthrough the side wall of the water-reservoir. All of the pipe is thusabove the bottom of the water-reservoir, and the structure may thus beset upon any structure, and it is not necessary to provide means forplacing the receptacles for the milk and cream beneath the bottom of thestructure. In producing the separable connection I preferably provide anozzle at the lower end of the milkreservoir adapted to fit in a socketprovided in connection with the portion of the exitpipe mounted upon thewater-reservoir.

I have illustrated my invention in the accompanying drawings, in whichFigure 1 is a sectional View of a creamseparator embodying my invention.Fig. 2 is a plan view thereof. Fig. 3 is a sectional view on line 3 3,Fig. 1. Fig. 4 is a sectional view of the separable connection. Fig. 5is a sectional View of a modified form of the separable connection.

Like letters refer to like parts in the several figures.

' The water-reservoir a may be constructed in any desired manner and ispreferably formed with windows or panes a a, of glass or mica, at oneend in order that a view may be had of the interior. Within thereservoir (0 the milk-reservoir b is adapted to rest, this reservoirhaving similar panes 7) b at one end registering with the panes a a. Themilkreservoir is oblong and hollow in order that the chilling effect ofthe ice or water in the water-reservoir may readily penetrate allportions of the contents of the milk-reservoir.

The bottom Z2 of the milk-reservoir is of V- shape in cross-section andslants toward the forward end. A leg 7) supports the rear end of themilk-reservoir.

Secured to the bottom of the milk-reservoir at the forward end is anozzle 0, secured to the bottom of the reservoir by solder or in anypreferred manner. The nozzle carries near the end a peripheral channel,in which fits a packing-ring 0, of rubber or similar material. Thenozzle is adapted to enter a tapered recess 0 formed in the end of thepipe 0. When the nozzle is inserted in the recess, the packing-ring iscompressed, and thus serves to effectually prevent the passage of thewater in the water-reservoir to the interior of the exit-pipe. he faucet(Z is secured to the end of the pipe 0 in any preferred manneras, forinstance, by threads or by solder. The faucet may be of any preferredform, and I have shown a form which is commonly used for this purpose inwhich a tapered stem CZ, carrying at the end a handle d, fits in acorrespondingly-tapered bore. The stem d carries in the end a bore d,communicating with a port (1*. When the stem (Z is rotated into oneposition, the port (F affords a communication between the bore d" andthe opening through the exit-pipe, while when the stem (Z' is partiallyrotated the port (1 is carried out of communication with the openingthrough the exit-pipe, and the exit-pipe is thus sealed. The separableexit-pipe as thus constructed consists of but a few simple parts, whichmay be readily cleansed. It is of the utmost importance that thestructure be such that there will be no corners or crevices in whichdirt may lodge, and the structure herein described has been found inpractice to afford no opportunity for the accumulation of dirt, iffrequently cleansed.

Near the upper end of the water-reservoir a number of inwardly-extendinglugs (1, a are provided, and the cross-pieces a are adapted to rest uponthe top of the milk-reservoir, with the ends thereof beneath the lugs toa to thereby secure'the milk-reservoir firmly in position. When it isdesired to remove the milk-reservoir, the cross-pieces a a are removed,and the milk-reservoir may then be lifted out of the water-reservoir,the nozzle 0 readily withdrawing from the socket 0. WV hen it is desiredto replace the milk-reservoir, the same is inserted in position, so thatthe nozzle will enter its socket, and the pressure exerted by thecross-pieces a" a when placed in position will force the nozzle firmlyinto the socket.

A cover 0 is adapted to rest upon the top of the water-reservoir. Thiscover is preferably made funnel-shaped and provided with an opening a atthe center, across which is stretched a sieve 6 The opening a affordsventilation when the cover is in position, and by turning the coverupside down the same may be used as a strainer, and the milk may bepoured into the cover, thus acting as a funnel, and is thus directedthrough the sieve 0 into the milk-reservoir.

In Fig. 5 I have illustrated a modification in which a shoulder a isprovided upon the nozzle 0, against which a second packing-ring c isadapted to rest, and when the nozzle is inserted in the socket c thepacking-ring c is compressed between the shoulder 0 and the end of thewall surrounding the socket 0 A double surety against the leakage of thewater or the milk is thus provided. Instead, however, of providing bothpackingrings either of the packing-rings may be omitted and the otherdepended upon for producing the water-tight joint. By extending theexitpipe 0'' through the side wall of the can the can may be seated uponany flat surface, such as a bench or floor, and does not require anespecially built-up support, as where the outlet is in the bottom of thecan.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is*

1. In a cream-separator, the combination with an outer water-can, of acan for milk arranged within said outer ean and having a slopingbottom,a socket within said outer can, a faucet arranged exteriorly of saidouter can and connected with said socket, a nozzle carried at one end ofsaid inner can, said nozzle being detachably connected to said socketand forming a support for one end of said inner can, a leg supportingthe other end of said inner can and coacting with said socket tomaintain said inner can in an upright position in said outer can, andmeans to hold said inner can in said outer can and retain said nozzle insaid socket whereby said inner can is held against being raised by thewater in said outer can and atight connection is maintained between saidnozzle and said socket.

2. In a cream-separator, the combination with an outer water-can, of acan for milk arranged within said outer can and having a sloping bottom,a socket within said outer can, a faucet arranged ext eriorly of saidouter can and connected with said socket, a nozzle carried at one end ofsaid inner can, said nozzle being detachably connected to said socketand forming a support for one end of said inner can, suitable means forsupporting said inner can in an upright position in said outer can, andmeans to hold said inner can in said outer can and retain said nozzle insaid socket whereby said inner can is held against being raised by theWater in said outer can and a tight connection is maintained betweensaid nozzle and said socket.
